21.4 Functional description
21.4.1 eDMA basic data flow
The basic flow of a data transfer can be partitioned into three segments.
As shown in the following diagram, the first segment involves the channel activation:
454
BITER
14–0
Field
value extends to 15 bits in place of a link channel number. If the major loop is exhausted, this link
mechanism is suppressed in favor of the MAJORELINK channel linking.
NOTE: When the software loads the TCD, this field must be set equal to the corresponding CITER field.
0
1
Starting Major Iteration Count
As the transfer control descriptor is first loaded by software, this 9-bit (ELINK = 1) or 15-bit (ELINK = 0)
field must be equal to the value in the CITER field. As the major iteration count is exhausted, the contents
of this field are reloaded into the CITER field.
NOTE: When the software loads the TCD, this field must be set equal to the corresponding CITER field.
DMA_TCDn_BITER_ELINKNO field descriptions (continued)
The channel-to-channel linking is disabled
The channel-to-channel linking is enabled
Otherwise, a configuration error is reported. As the major iteration count is exhausted, the
contents of this field is reloaded into the CITER field.
Otherwise, a configuration error is reported. As the major iteration count is exhausted, the
contents of this field is reloaded into the CITER field. If the channel is configured to execute a
single service request, the initial values of BITER and CITER should be 0x0001.
